Dyesol Achieves Technical Breakthrough in Solid-State DSC

Business Wire
Dyesol, the world leader in the commercialisation of Dye Solar
Cell (DSC) technology, has achieved a "game changing" technical
breakthrough by achieving a solid-state DSC efficiency of 11.3%
at full sun.
The breakthrough comes as the technology transitions from
liquid-based to solid-state systems to meet the demands of product
life and mass manufacture. The variation in technology, known as
mesoscopic solar cells, meets the technical challenges of mass
manufacturing Building Integrated Photovoltaic (BIPV) products and
will allow Dyesol and its multi-national commercialisation partners
to confidently address the multi-billion dollar global market.
In 2010, solid-state DSC performance was at a mere 5%,
significantly lagging the performance of liquid based systems.
However, the subsequent technical advancement has been nothing
short of revolutionary. Dyesol, through the work of its scientist
Dr Peng Qin, based at the École Polytechnique Fédérale de Lausanne
(EPFL) in Switzerland, has achieved solid-state DSC laboratory
efficiency of 11.3%. Dyesol is also confident of achieving
industrial efficiencies greater than 10% because of the added
simplicity of working with solid-state systems. At this level of
module performance the technology will be grid competitive - the
"holy grail" for renewable energy technologies.
This achievement is particularly important in solar markets
where light conditions are sub-optimal, such as Europe, North
America and North-East Asia, where Dyesol technology has a
considerable advantage over 1st and 2nd generation photovoltaic
technologies.
Chairman Richard Caldwell said: "The business case for solar
remains compelling, however there is every reason to question which
technologies will emerge from the current solar industry maelstrom
as winners. Today's announcement represents a quantum leap for
Dyesol and its' commercialisation partners and we look forward
to a rapid transition from the laboratory to the production
line".
Dyesol has been working closely with R&D partner, the EPFL,
and is confident of announcing further improvements in solid-state
performance in the near term. Remarkably, solid-state performance
is confidently expected to outperform all hitherto known and
published liquid-based efficiencies. DSC inventor and EPFL
Professor, Michael Graetzel, is speaking at the HOPV Conference in
Seville, Spain this week where he will be discussing some of the
latest technological developments.

About Dye Solar Cell Technology
DSC technology can best be described as 'artificial
photosynthesis' using an electrolyte, a layer of titania (a pigment
used in white paints and tooth paste) and ruthenium dye deposited
on glass, metal or polymer substrates. The term mesoscopic has been
introduced to reflect further advances in the technology,
particularly where a perovskite is substituted for dye as a
sensitiser. Light striking the sensitiser excites electrons which
are absorbed by the titania to become an electric current. Compared
to conventional silicon based photovoltaic technology, Dyesol's
technology has lower cost and embodied energy in manufacture, it
produces electricity more efficiently even in low light conditions
and can be directly incorporated into buildings by replacing
conventional glass panels or metal sheets rather than taking up
roof or extra land area.
